Narrator: This is Science Today. New studies reveal that age-related neurological decline affects men more than women. Dr. Ari Green, an assistant professor in the Department of Neurology at the University of California, San Francisco, co-led the study.
Green: What we discovered is that the speed of conduction that occurs, it's known to decline with age, so we can see that it's lower in people who are older than people who are younger. But one of the very interesting things we found is that is particularly prominent in men. And the place we saw it most prominently in this age group is in the nerve segments that are closest back to the spinal cord — in men who are older.
Narrator: Green says their study also found declines in neurological function were not just a consequence of aging and gender, but also metabolic factors, such as blood sugar levels, which may be modifiable.
Green: It points us towards understanding how might these metabolic factors drive neuronal survival and function and how might it affect survival and function associated with age.
